SERVICE
Before attempting any maintenance or removal of the guards, stop the engine, switch off
the fuel supply and remove the spark plug lead from the spark plug. Two 6mm nuts and
bolts hold the metal belt guard in place.
Fit only genuine components to this machine.
After every use always clean the machine, ensuring that the core tines are free of soil, and
lightly oil the inside and outside of the core tines with vegetable oil. This ensures the cores
are ejected easily when operated the next time, resulting in better penetration of the turf.
Check that the tine fixing u-bolt ad nuts are tightened correctly.
To replace tines, loosen and remove the flange nuts, remove the saddles and the u-bolt
from the tine and slide the tine forward. To install the new tines, reverse this operation.
LUBRICATION
1. There are 3 grease fittings on this aerator; one near the center of the tine reel, and one
on each wheel. We suggest that these points be lubricated after each days operation.
2. Oil the chain and check its tension.
3. Grease wheel bearings.
4. Oil clutch lever and belt tightening pivot bar.
